Definitions

  • the invention relates to the use of a multilayer film with adhesion-enhancing additive as a back cover for solar modules.
  • Solar modules often referred to as photovoltaic modules, are used for generating electrical energy from sunlight and consist of a laminate containing a solar cell system as the core layer. This core layer is encased with encapsulating materials which serve as protection against mechanical and weather-related influences.
  • the active solar cell is in this case between a front cover and a rear cover.
  • the front cover is translucent and is usually made of glass; it is bonded to the layer containing the solar cell by means of a primer layer, which often consists of an ethylene-vinyl acetate copolymer.
  • the back cover ensures electrical shielding and serves as protection against the effects of the weather, such as UV light, and as a moisture barrier.
  • foil composites of fluoropolymer films and polyester are currently used by default.
  • the fluoropolymer film on the outside guarantees the weather resistance, the polyester film the mechanical stability and the desired electrical insulation properties.
  • Another fluoropolymer film on the inside serves for the connection to the sealing layer of the solar cell system.
  • such fluoropolymer films have only a low adhesion to the sealing layer, which is used as an embedding material for the solar cell itself.
  • the fluoropolymer film contributes only to a lesser extent to the electrical insulation, resulting in the necessity of using a comparatively thick polyester film.
  • thermoplastic layer contains a light-reflecting filler such as titanium dioxide, while the solar cell facing away from the thermoplastic layer contains a second filler, such as glass fibers, wollastonite or mica, which causes a higher thermal conductivity of this layer.
  • exemplary thermoplastics come from the group of polyamides, polyesters or blends of polyamide and polyolefin. Explicitly mentioned are PA11, PA12 and PA1010 as well as their blends with polyolefins.
  • Such photovoltaic modules have a service life of at least 20 years. During this period, the interlaminar liability must be maintained as far as possible. This applies on the one hand for the connection of the rear foil to the sealing layer containing the actual solar cell and on the other hand also for the adhesion of the individual layers of the back foil to one another. If the same polyamide is used in the polymer portion of the backsheet in all layers, a very good adhesion is generally achieved. However, the polymer portion of the middle layer often consists of blends of polyamides and polyolefins for cost reasons. Such composites may, due to the polyolefin content, have a lower level of adhesion output, but in particular the level of adhesion decreases more rapidly over time as compared to pure polyamide systems.
  • the object of the invention is therefore to improve the adhesion between purely polyamide-based layers and those containing polyamide and polyolefin in rear sheets of photovoltaic modules.
  • EP 1 884 356 A1 describes a multi-layer composite in the form of an extruded hollow profile, in which the outer layer consists of a mixture based on a polyamide and a polyamide elastomer, which leads to a higher elongation at break at higher extrusion speeds.
  • These hollow profiles are used as lines in the automotive sector.
  • polyamide elastomer is contained only in the layer according to b).
  • polyamide elastomer is contained only in the layer according to c).
  • polyamide elastomer is contained both in the layer according to a) and in the layer according to c).
  • polyamide elastomer is contained both in the layer according to a) and in the layer according to b).
  • polyamide elastomer is contained both in the layer according to b) and in the layer according to c).
  • polyamide elastomer is contained both in the layer according to a) and in the layers according to b) and c).

  • PPA polyphthalamide

  • Suitable PPAs are, for example, PA66 / 6T, PA6 / 6T, PA6T / MPMDT (MPMD stands for 2-methylpentamethylenediamine), PA9T, PA10T, PA11T, PA12T, PA14T and copolycondensates of these last types with an aliphatic diamine and an aliphatic dicarboxylic acid or with an ⁇ -aminocarboxylic acid or a lactam.
  • Semicrystalline polyamides have a melting enthalpy of more than 25 J / g, measured by the DSC method according to ISO 11357 at the 2nd heating and integration of the melt peak.
  • the polyolefin of the layer according to b) is, for example, polyethylene or polypropylene.
  • any commercially available type can be used.
  • the polyolefin may also include an impact modifier such as. EPM or EPDM rubber or SEBS; it can be prepared by any known method, for example by Ziegler-Natta, by the Phillips method, by means of metallocenes or radically.
  • the polyolefin may contain functional groups for better attachment to the polyamide; additionally or alternatively, a compatibilizer may be added.
  • Suitable functional groups are e.g. Acid anhydride groups, N-acyl lactam groups, carboxylic acid groups, epoxide groups, oxazoline groups, trialkoxysilane groups or hydroxyl groups.
  • the functional groups can be introduced either by copolymerization of a suitable monomer together with the olefin or by a grafting reaction. In the grafting reaction, a preformed polyolefin is reacted in a known manner with an unsaturated, functional monomer and advantageously a radical donor at elevated temperature.
